CAR-SEAT.

SEClIFlQ/ATION forming pari'. Of Letters Patent N0. 696,095, dated. March 25, 1 902. Application tiled July 12, 1901. Serial No. 67,954.. (No model.)

To all whom, it may concern,.-

Be it known that I, GEORGE W. DRYER, a citizen ofthe United States, and a resident of New York cit v,in the cou'ntyan'd State of New York, have invented certain new and useful Improvements in Car-Seats, of which the following is a specification, reference being had to the accompanying drawings, in which the same reference characters refer to similar parts throughout the various ligu res.

My invention relates to car-seats of the walk-over type, in which the seat-back is shifted bodily without reversing the same, so that opposite sides of the seat-back come into operation as the seat is shifted.

Figure l is a side sectional View of my car- Fig. 2 is a longitudinal section of the same. Figs. 3, 4, and 5 are partial sectional views showing in detail the operating mechanism for shifting the seat. Figs. 6 and 7 are similarviews showing a' modified form of my operating mechanism.

Upon suitable legs A is mounted the seatframe, composed of end pieces A2 andlongi-v tudinal side pieces A', securely fastened together to form a rigid frame. The arms A3 are secured in any usual manner to the piecesy A2. The seat endsB, formed of cast-iron or other suitable material, are rigidly secured to the seat-frame and supportthe yoperating mechanism as well as the seat cushion and back. The seat end isformed of a plate ot' material having suitable strengthening-ribs cast upon it and also thesupporting-ribs B and B2, formed as is indicated in Fig. 3 of the drawings. The two bearings B2 and B4 are formed by castingbearing-lugs on the seat end. The, rocker-lever E is pivotally connected to the seat end by abearing-bolt E', secured to the bearing AB4 in the seat end in any desired manner. The upper lever D is secured to the bearing B3 in a similar manner. These two levers are pivotally connected at their outer or free ends to the headpiece F. In the upper -lever D are mounted the two pivots D2 on either side of the pivot D and substantially in a line perpendicular to the central line of this upper lever. The two pivots E2 are similarly mounted on the rocker V lever E, although they are at a less distance from the pivot E4 than are the pivots D2from ends, one at either end of the seat-frame, and

that the operating mechanism which I have just described is formed in duplicate, one set mounted on each of the seat ends, as isshown in Fig. 2. The tubular rod E4 serves to connect these twovv sets of operating mechanism and insures their operating in unison, so that both ends ofthe seat-back are shifted together. Y A

A rocker C rests at its lower inclined side C2 upon the ribs B2 of each of the seat ends, and the seat-cushion C, mounted on a suitable frame, is rigidly secured at either side to lugs C on these rockers. The rockers have formed in the central parts of the same,

the slot'CS, in which the tubular rod E4 Works, and as it moves therockers and the seat-cushion are moved laterally of the seat .to adjust'the seat-cushion in proper position by reason of the engagement of this rod with the guiding-pieces forming the `slot. The back-cushion, with its frame, is of course rigidly-secured to the headpiece F on either side of the cushion.

ln the m'od'iiied form of my car-seat shown in Figs. 6 and 7 the stub-shaft E8 has bearing in the bearing-lug on the seat end, and the cylindrical extension E6 in this case is coincident with the axis of this shaft. The tubular rod E7 is secured to the extension E6 by bolts on either side of the seat, as in the other form. The rocker-leverin this case is formed with a cam E5 of elliptical shape, as shown in Fig. 6, or of any other eccentric form, which engages with the 'slotrC4 in the rocker and moves the rocker and seat laterallyasthe rocker-lever is rotated.

The operation of my seat is 'as follows: When it is desiredl to reverse the position of the seat,'the seat-back is pushed bodily in the desired direction, and this raises the seat Ioo mechanism, since the headpiece F is linked to the levers D and E into the positions shown in Fig. 4, where the headpiece and levers are in the same line. Further movement tends to thror the upper lever over, and this lever being connected with the rocker-lever by the links G rotates this lever in the same direction, thus insuring the proper reversal of the seat. It will be noted that the seat and rockers are moved in the opposite direction from that in which the back is moved through the eccentric projection on the rocker-lever engagin g the slot in the rocker, so that the rockers and seat are moved laterally and at the same time tilted as the seat is reversed. It will be seen by reference to Fig. 3 that the upper lever D engages with and is supported by the ribs B on either side of the seat end, thus sustaining the weight of the headpiece and seat-back. Since it is desired that the headpiece F shall take an inclined position, it is necessary that the rocker-lever E be moved through a greater angle than the upper lever D, and to accomplish this result the distance between the pivots D2 must be greater than that between the pivots E2, as has been set forth.

Numerous modifications may be devised by those skilled in the art. Also parts of my device may be used in connection with other devices whieh are well known in the art, and I do not Wish to be limited to the exact form of seat which I have disclosed.

Vhat is claimed as new is- 1. In a car-seat, seat ends having supporting-ribs formed thereon, rocker-levers and upper levers pivoted to said seat ends, said upper levers being longer than said rockerlevers, curved links pivoted to said upper levers and said rocker-levers, the link-pivots of said upper levers being farther from the center of said upper levers than the link-pivots of said rocker-levers are from the center of said rocker-levers, a seat-back pivotally connected to said rocker-levers and said upper levers, a rod to connect said rocker-levers, seat-rockers supported upon said seat ends and formed with guiding-pieces and eccentrically-mounted projections on said rockerlevers to engage said guiding-pieces.

2. In a car-seat, a seat end having supporting-ribs formed thereon, a rocker-lever pivoted to said seat end, an upper lever pivoted to said seat end, a link pivoted to said upper lever and said rocker-lever, the link-pivot of said upper lever being farther from the center of said upper lever than the link-pivot of said rocker-lever is from the center of said rocker-lever, a seat-back pivotally connected to said rocker-lever and said upper lever, said rocker-lever being shorter than said upper lever, a seat-rocker movably supported upon said seat end and formed With guiding-pieces and an eccentrically-mounted projection on said rocker lever to engage said guidingpieces.

3. In a car-seat, a seat end formed with supporting-ribs thereon, a rocker-lever pivoted to said seat end, an upper lever longer than said rocker-lever pivoted to said seat end, said levers being adapted to be pivotally connected at their ends to a seat-back, a link pivoted to said upper lever and said rocker-lever, the link-pivot of said upper lever being farther from the center of said upper lever than the link-pivot ot' said rocker-lever is from the center of said rocker-lever, said upper lever being adapted to be supported by said supporting-ribs, a seatrocker movably supported upon said seat end and formed with guidingpieces and an eccentrically-mounted projection on said rocker-lever to engage said guiding-pieces.

4. In a car-seat, a seat end, formed with su pporting-ribs, a rocker-lever pivoted to said seat end, an upper lever pivoted to said seat end, a link pivoted to said upper lever and said rocker-lever, the link-pivot of said upper lever being farther from the center of said lever than the link-pivot of said rockerlever is from the center of said rocker-lever, a seat-back pivotally connected to said rockerlever and said upper lever, said rocker-lever being shorter than said upper lever.

5. In acar-seat, a seat end formed with supporting-ribs thereon, a rocker-lever pivoted to 4said seat end, an upper lever longer than said rocker-lever pivoted to said seat end, said levers being adapted to be pivotally connected at their ends to a seat-back, a link pivoted to said upper lever and said rocker-lever, the link-pivot of said upper lever being farther from the center of said upper lever than the link-pivot ot said rocker-lever is from the center of said rocker-lever, said upper lever being adapted to be supported by said supporting-ribs.

6. In a car-seat, a seat end formed with two sets of supporting-ribs thereon, a rocker-lever pivoted to said seat end, an upper leverlonger than said rocker-lever pivoted to said seat end, the free ends of said levers being adapted to be pivotally connected to a seat-back, a link pivoted to said rocker-lever and said upper lever, the distance of said link-pivot of said rocker-lever from the center of said rockerlever being less than the distance of the linkpivot of the upper lever from the center of said upper lever, a seat-rocker having an inclined lower surface engaging with the second set of said supporting-ribs, guiding-pieces formed on said seat-rocker and an eccentric projection on said rocker-lever engaging said guiding-pieces to shift and tilt said seat-rocker.
